struts2和hibernate的配置我这里就不多说了,先把两个有关的东西说下。一个是所有的包。struts2+hibernate3+spring2.5我包准备放上去给大家下载。

放在的我百度云盘里面

闲话不说:开始。

先是struts2和hibernate的配置

web.xml:

<?xml version="1.0"encoding="UTF-8"?>
<web-app version="2.5"xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <!-- structs2的配置 -->
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>
            org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
 
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
 
</web-app>

 然后在src下添加一个struts.xml:

复制代码
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC  "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"  "http://struts.apache.org/dtds/struts-2.0.dtd"><struts></struts>
复制代码

 然后在src下添加一个hibernate.cfg.xml:(这是一些数据库的配置)

复制代码
<?xml version='1.0' encoding='UTF-8'?><!DOCTYPE hibernate-configuration PUBLIC  "-//Hibernate/Hibernate Configuration DTD3.0//EN"  "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"><!-- Generated by MyEclipse Hibernate Tools.  --><hibernate-configuration>    <session-factory>        <property name="connection.username">sa</property>        <property name="connection.url">            jdbc:jtds:sqlserver://localhost:1433;DatabaseName=LQQ        </property>        <property name="dialect">            org.hibernate.dialect.SQLServerDialect        </property>        <!--<property name="myeclipse.connection.profile">            LoginSystem            </property>  -->        <property name="connection.password">sa</property>        <property name="connection.driver_class">            net.sourceforge.jtds.jdbc.Driver        </property>        <property name="show_sql">true</property>        <!-- POJO 类映射配置-->        <mapping resource="sedion/xq/ORM/Stuinfo.hbm.xml" />    </session-factory></hibernate-configuration>
复制代码

重点讲Spring:
1. src下面新建applicationContext.xml文件:

 

复制代码
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"><!-- 这是个例子待会会用到  可以先不要 -->    <bean id="TUser_id" class="test.TUser">        <property name="username" value=""></property>        <property name="allname" value=""></property>        <property name="address" value="温州市"></property>    </bean>    </beans>
复制代码

 然后在web-xml:

<context-param>
         <param-name>contextConfigLocation</param-name>
        <!--spring 的配置文件加载路径-->
          <param-value>classpath:applicationContext.xml</param-value>
</context-param>

 

2.Spring基本配置完毕

下面我们测试下:src建个test包

建两个类User和SpringTest类:

 

复制代码
public class User implements java.io.Serializable {    /**     *      */    private static final long serialVersionUID = 1L;    private String username;    private String allname;    private String address;    public String getUsername() {        return this.username;    }    public void setUsername(String username) {        this.username = username;    }    public String getAllname() {        return this.allname;    }    public void setAllname(String allname) {        this.allname = allname;    }    public String getAddress() {        return this.address;    }    public void setAddress(String address) {        this.address = address;    }
复制代码

 

 

public class SpringTest {
    publicstatic void main(String[] args) {
        // 加载spring配置文件,初始化IoC容器
        ApplicationContext ac =new ClassPathXmlApplicationContext(
                "applicationContext.xml");
        // 从容器 接管Bean
        TUser user = (TUser) ac.getBean("TUser_id");
        // 输出欢迎信息
        System.out.println("Hello:"+ user.getUsername() + ";u is in "
                + user.getAddress() +" ; and u is  " + user.getAllname());
    }
}
<br><br>

 

别忘了:applicationContext.xml中配置一个bean,在xml中增加如下代码:

 

<!-- 这是个例子待会会用到  可以先不要 -->
  <bean id="TUser_id"class="test.TUser">
        <property name="username"value="你"></property>
        <property name="allname"value="李"></property>
        <property name="address"value="温州市"></property>
    </bean>

 

 

 

运行main方法后

控制台出现:Hello:你;u is in 温州市 ; and u is  李

下面开始整合

整合struts2

  1.整合struts2配置web.xml文件。在web.xml中加入以下代码:

 

<!-- Spring与Struts的整合其实就是把Struts的Action类交给Spring来管理 -->
<listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener  
    </listener-class>
</listener>

 

 2.举个例子:

  把strutsaction交给spring:

  先把 

<action name="login"class="test.LoginAction ">

 改为

<action name="login" class="loginAction_id">

 

 

然后在

applicationContext.xml中增加如下代码:

 

<bean id="loginAction_id"class="test.action.LoginAction"scope="prototype">
</bean>

 

 

整合Hibernate

 Spring整合Hibernate主要是对hibernateSession进行管理,包含Session的创建、提交、关闭的整个生命周期。Spring对事务的管理应用了AOP的技术

1)       配置sessionFactoryspring来创建Session

我们原来是用HibernateSessionFactory.java来创建Session的,现在删除即可,交给Spring创建。(这样就spring来整合hibernate来创建session)

这里,创建了一个Session工厂类的Bean,其ID为“sessionFactory”.

 

applicationContext.xml中增加如下代码:

 

<!-- 配置sessionFactory -->
 
 <bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
 
     <property name="configLocation">
 
         <value>classpath:hibernate.cfg.xml</value>
 
     </property>  
 
 </bean>  

 

还有个例子上的配置:

<bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource"ref="dataSource"></property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
        <property name="mappingResources">
            <list>
                        <value>sedion/xq/bean/User.hbm.xml</value><!--这里是将映射文件加载-->
            </list>
        </property>
 
    </bean>

 

2.

然后DAO层匹配一个session工厂,<ref bean="sessionFactory"/>这个sessionFactory是指session工厂的ID。

 

<bean id="userDao"class="sedion.xq.dao.iml.UserDAOImpl"scope="singleton">
 
        <property name="sessionFactory">
            <ref bean="sessionFactory"/>
        </property>
</bean>

 

 3.service层注入DAO层

     <bean id="userService"class="sedion.xq.sevice.iml.UserServiceImpl">
    <property name="userDAO"ref="userDao"></property>
</bean>

 然后就是各个action注入service层:(随便写个)

<bean id="saveUesrAction"class="sedion.xq.action.user.SaveUserAction"
    scope="prototype">
    <property name="userService"ref="userService"></property>
</bean>
